Application October 9,

1 Claim.

The device forming the subject matter of this application is a bottom frame for spring beds. One object of the invention is to provide novel means whereby the ends` of the hangers may be assembled with the side portions of the frame in such a way that the ends of thehangers will be housed, out of sight, beneath the horizontaloutstanding flanges of the frame, the upper surface of the said anges being smooth.

It is Within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention apper- .tains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction .hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without ,departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows, in top plan, a bottom frame for spring beds constructed in accordance with the invention;

Fig. 2 is a side elevation of the frame;

Fig. 3 is an end elevation of the frame;

Fig. 4 is a transverse section showing a step in the assembling of the frame;

Fig. 5 is a transverse section showing an advanced step in the assembling of the frame;

Fig. 6 is a perspective View showing a portion of one of the side members of the frame, and a portion of one of the hangers, prior to the assembly of those parts.

The article forming the subject matter of this application preferably is made of metal throughout. It comprises two U-shaped frame members I, shown in outline in Fig. 1. The frame members I comprise parallel side pieces 2, supplied at their ends with inwardly projecting arms 3 arranged at right angles to the side pieces 2. The side pieces 2 and the arms 3 preferably are angle members. The side pieces 2 (Fig. 6) comprise outwardly extended or first flanges 4, and depending or second flanges 5, arranged at right angles to each other. The inwardly projecting arms 3 comprise outwardly extended or first fianges 6 (Fig. 1) and depending or second ilanges 1 (Fig. 4). 'I'he flanges 6 and 'I are arranged at right angles to each other. The end surfaces of the arms 3 are marked by the numeral 8 in Fig. 4. The arms 3 are joined together securely, at their end surfaces 8, by any suitable means, preferably 19374, serial No. 747,590

electrical welding, indicated at I0. Figure 6 Y shows that the depending iianges 5 of the side pieces 2Vhave openings 9, in the form Vof elongated slots, and there may be any desirednumber of these openings.

Hangers II, in the form of bars, are provided. Hangers like the hangers II functionally, but differing from them structurally are common, and the usual practice'is to place the ends of the hangers on top of the flanges 4 of the side pieces 10 V2 and rivet them inA place, a'constructin not shown in the drawings, because it is well understood by those skilled in the art. The disadvantage incident to the construction last above referred to is that the upper surfaces of the flanges 15 4 of the side pieces 2 are not smooth. One object of this invention is to provide a novel means for assembling the hangers with the side pieces 2 and still have the upper surfaces of the flanges 4.0i the side pieces smooth.

Having the foregoing consideration in mind, each hanger II comprises a body I2 in the form of a bar having its greater transverse dimension disposed vertically. The body I2 is twisted as shown at I4, to form end portions I6 having their 25 greater transverse dimensions arranged at right angles to the greater transverse dimension of the body I2, that is, horizontally. The end portions I6 are connected to the ends of the body I2 by upwardly inclined parts I5. Hooks I9 are formed 30 at the ends of the parts I6 of the hangers I I, and these hooks include depending bills II, shown in Fig` 6. The hooks I9 are a little narrower than the end portions I6, and, consequently, shoulders I8 are formed at the ends of the parts I6, on each 35 side of the hooks I9. The hooks I9 extend outwardly through the openings 9 in the anges 5 of the side pieces 2, and the flanges 5 are located between the bills I 'I of the hooks I9 and the shoulders I8, the shoulders I8 cooperating with 40 the inner surfaces of the flanges 5, and the bills I1 of the hooks cooperating with the outer surfaces of the said flanges.

It will be obvious, from what has been stated last hereinbefore, that the connections between 45 the hangers I2 and the side pieces 2, represented by the bills I'I of the hooks I9, are located out of sight, below the anges 4 of the side pieces 2, the upper surfaces of the flanges 4 being left smooth and unencumbered, which is a desirable construc- 50 tion.

Up to this point, the device has been discussed only as to its actual structural make-up. The utility of the structure resides not only in the bottom frame, considered as a complete article 55 ...www-W of manufacture, but, as well, in the expeditious Vand convenient way in which its constituent parts may be assembled. In this connection, reference should be had to Figs. 4 and 5 of the drawings. In the gures alluded to, Va templet is provided for, facilitating the making ofthe bottom frame shown in Fig. l; Y NoV attempt has been made to show a templet which will suit everyone, and the disclosure of the templet is to be regarded as sug-v gestively useful, rather than mandatory.

As depicted, but not of necessity,

Finally, the ends 8 of the arms 3 are connected tothe templet "claimed is :Y

otherwise,` and the frame is complete, aside from the mounting of the suspension brackets 20 of Fig.

7, which may be accomplished as a final step in e the making of the complete frame. Y f The general structure is simple but useful, and

the method shown in Figs. 4 and 5 will be Vfound to be highly advantageous and time saving, in the making of the spring bed frame. Y

One advantage of the invention is that it effects Aa marked saving material, in that no rivets need be used, Vandthere is a corresponding Vsaving labor, since riveting is" necessary.
